    Användbarhet inom människa-datorinteraktion i praktiken: En kartläggning av utvärderingsmetoder2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att kartlägga yrkesverksammas preferenser och användning av utvärderingsmetoder för användbarhet inom människa-datorinteraktion. En webbenkät distribuerades via epost till företag med minst en anställd som arbetar med användbarhet samt via sociala medier genom intresseorganisationen STIMDI och företaget Inuse. Totalt erhölls 104 svarande varav en räknades som bortfall då den ansågs vara en dubblett. Resultaten visar att ingen enskild eller kombination av metoder används oftast och rankas ge högst effekt på användbarhet. Angående vilka utvärderingsmetoder som används är intervju och tänka högt med användare de två metoder som nämns av flest deltagare. Resultaten visar även att nästan 80 % skattar användning av utvärderingsmetoder och involvering av användare i deras arbete som mycket viktigt. En tydlig preferens för att involvera användare och arbeta med kombinationer av metoder framgår i denna kartläggning. Forskning bör möjligtvis fokusera mer på hur användandet av utvärderingsmetoder sker i kombination.

    Untangling Road Trip Experiences with Conected Car: Planning and bringing it to the car2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With developing technologies and growing infrastructures, connected experiences are expanding their realms towards various devices and scenarios in our lives. One of the areas, which is going under a big change due to this connectivity is the car related experiences. As connectivity is intrinsically enabler of different experiences and services, it is foreseen that it will bring a different dimension to car and driving related experiences as well.By investigating the future trends and possibilities that connectivity can provide to car and driving related experiences, this thesis aims for imagining the near future scenarios with an explorative approach, focusing on one and addressing to the rising issues with a design proposal that is meaningful to both users and the industry.The result, Tripcloud, contributes to the future scenario of having a road trip with the car, with a new digital platform that aims for supporting the users throughout the planning and bringing the plans into the car experience seamlessly and safely. It aims for reducing today’s existing complexity in terms of interaction and cognition to provide a better experience and avoid driver distraction. With providing organised information pieces, information exchange between people and automated links with mobile devices and car, Tripcloud offers easier an more convenient alternative for road trip planing and bringing the plans into car experiences for the near future.

    Sustainable development for mobile health applications using the human-centered design process2023In: JMIR Formative Research, E-ISSN 2561-326X, Vol. 7, article id e45694Article in journal (Refereed)
    Abstract [en]

    Well-documented scientific evidence indicates that mobile health (mHealth) apps can improve the quality of life, relieve symptoms, and restore health for patients. In addition to improving patients' health outcomes, mHealth apps reduce health care use and the cost burdens associated with disease management. Currently, patients and health care providers have a wide variety of choices among commercially available mHealth apps. However, due to the high resource costs and low user adoption of mHealth apps, the cost-benefit relationship remains controversial. When compared to traditional expert-driven approaches, applying human-centered design (HCD) may result in more useable, acceptable, and effective mHealth apps. In this paper, we summarize current HCD practices in mHealth development studies and make recommendations to improve the sustainability of mHealth. These recommendations include consideration of factors regarding culture norms, iterative evaluations on HCD practice, use of novelty in mHealth app, and consideration of privacy and reliability across the entire HCD process. Additionally, we suggest a sociotechnical lens toward HCD practices to promote the sustainability of mHealth apps. Future research should consider standardizing the HCD practice to help mHealth researchers and developers avoid barriers associated with inadequate HCD practices.

    Enhancing content discovery in Video on Demand services for children2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The media landscape is changing and Internet-based streaming services for children are becoming increasingly popular. The concept of online streaming extends freedom and control over content selection but discovering new content is often experienced as troublesome. The objective of this thesis is to identify parameters to make it easier for users of streaming services for children to discover and watch unfamiliar programs. Guidelines are formed based on literature studies, interviews, observations, a survey, a benchmark, data analysis with Adobe Analytics, a workshop and finally user tests with prototypes. These guidelines conclude that content should be categorized, dynamicized, highlighted and socially engaging. Categorization based on age is primarily important but interests and genres can also be used to make children more interested in a title. Content should be dynamic, customizable and personal to each user to give more accurate recommendations based on age and interests. Making one alternative more visually prominent will make this alternative more interesting especially for younger children and social features with information about other users opinions can motivate a decision to discover new content among older children.

    Effortless Charging: Enhancing Usability in Electric Car Mobile Applications2023Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In recent years, there has been an increased interest in the environment, and various efforts has been made in order to reduce human impact upon the planet. One such effort is transitioning the transport industry from using fossil-fuels to more sustainable fuels, such as electricity. This has led to a heightened interest in electric vehicles. Although electric vehicles have risen in popularity, they still face some challenges. One of these challenges is the lack of charging stations, and the hassle of charging the car. The complicated charging experience has even been expressed as a barrier, making some people hesitant to buy an electric vehicle. This calls for making the charging experience more intuitive and easy. One possible way to achieve this is by providing the drivers of electric vehicles with complementary tools, such as mobile applications, to aid them with charging. However, for these tools to be effective, it is important that they are designed with usability in mind. The focus of this thesis is enhancing usability in mobile applications for charging stations. In order to achieve this, a mobile application called Greencharge Infra is used as a case. The current design of this application is evaluated using Nielsen’s 10 heuristics of usability. Additionally, a user survey is sent out to representative users in order to better understand the user needs in these kinds of applications. Based on the findings from the evaluation and the user survey, and knowledge from established usability principles, a redesigned application is proposed. This proposal is later tested on representative users to ensure that the new design is living up to usability expectations. During the test, five criteria of usability are evaluated, these are efficiency, errors, satisfaction, memorability and learnability. The usability test result show that the new design of the application was efficient, induced few errors, was pleasant to use, and easy to learn. Therefore, the overall result of this thesis indicates that applying principles of usability in a real world case does work. The research has also led to wider understanding of how crucial usability is in mobile applications for charging stations.

    Autonomous vehicles for children with mild intellectual disability: perplexity, curiosity, surprise, and confusion2023In: ECCE '23: proceedings of the European Conference on Cognitive Ergonomics 2023, Association for Computing Machinery (ACM), 2023, article id 25Conference paper (Refereed)
    Abstract [en]

    Self-driving buses will be part of the public transportation system of the future, and they must therefore be accessible to all. The study reported in this paper examines the user experiences of 16 children with mild intellectual disability riding a self-driving bus. The qualitative analysis, performed by iterative affinity diagramming, of interviews, observations, and a co-design session with five of the children, suggests that familiar situations were characterized by contemplation and curiosity, while unfamiliar ones were characterized by surprise or confusion. The temporal structure of past, present, and future situations in the field of attention played a significant role in the children's experiences. This leads to design considerations for an explainable interior of self-driving buses.

    Reducing Food Waste with a Sustainable Lunch Concept: A Service Design Project2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Environmental problems such as pollution and overconsumption is something that is mentioned often in the news as this thesis is written. Food waste is a problem that causes valuable resources to be lost, as on average one third of all food globally is being wasted. The food chain is complicated, from the farm to the table, and innovations in all parts of the chain could help reduce the waste. We have aimed our scope to the end of the chain, when food is made at a restaurants to be served to customers. Figures say that about 23% of food in the restaurant business in Sweden is being wasted. To try to solve this problem, we have turned to service design and the methodologies presented there, to find a potential solution that could help reduce food waste.

    An extensive service design process was made with many interviews with restaurants to find where a solution could be made. The whole design process is presented in the report, and the final concept resolves around a sustainable lunch dish that can be made out of ingredients that would otherwise be thrown out. The dish would be sold at lunch restaurants for a reduced price since it is cheap to make, and would make more people act sustainable. A concept test was made to evaluate the the sustainable dish concept with the help from the public. The main question was:

    Is this concept something that could be adopted by people who buy lunch on a regular basis in Sweden?

    The concept test resulted in 165 respondents that were asked what they would choose to eat from a given menu. 32% chose the sustainable dish, and although biases were believed to have played a role in the decision, the concept was deemed successful. A website was then designed, aimed towards restaurants that wanted to adopt the concept and to get started in an easy way.

    ME|EMO: Application concept for sharing emotions through non-verbal communication2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    ME|EMO provides a method to help users to express, visualize and share emotions through digital nonverbal communication. This application will enable the users to map their emotions to colors and encourage users to paint their feelings. A canvas with uncolored images and a color palette with color coded emotions creates an environment for expressing and visualizing the feelings. The result is an image file in the form of a simple piece of modern art with the possibility of sharing it through social networks, or to record the emotions and save precious moments of life. Technology development, new ways of communication, digital tools, apps, social media, have helped people to have a better life by giving people the opportunity to communicate easier with loved ones and friends. ME|EMO tries to enhance the way of modern communication (digital text-based) such as social networks or modern healthcare systems, by supporting the emotional side of communications.

    EEG Analysis from Motor Imagery to Control a Forestry Crane2018In: Intelligent Human Systems Integration (IHSI 2018) / [ed] Waldemar Karwowski; Tareq Ahram, Springer, 2018, Vol. 722, p. 281-286Conference paper (Refereed)
    Abstract [en]

    Brain-computer interface (BCI) systems can provide people with ability to communicate and control real world systems using neural activities. Therefore, it makes sense to develop an assistive framework for command and control of a future robotic system which can assist the human robot collaboration. In this paper, we have employed electroencephalographic (EEG) signals recorded by electrodes placed over the scalp. The human-hand movement based motor imagery mentalization is used to collect brain signals over the motor cortex area. The collected µ-wave (8–13 Hz) EEG signals were analyzed with event-related desynchronization/synchronization (ERD/ERS) quantification to extract a threshold between hand grip and release movement and this information can be used to control forestry crane grasping and release functionality. The experiment was performed with four healthy persons to demonstrate the proof-of concept BCI system. From this study, it is demonstrated that the proposed method has potential to assist the manual operation of crane operators performing advanced task with heavy cognitive work load.

    Exploring HCI-issues within error- sensitive intensive healthcare systems: An Ethnographic case study2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    People are used to working routines that are taught and transferred from one to another, routines such as how to interact with an information system and how to use it in a specific context. While user experience and usability have been two issues of interest within the field of HCI, there is a lack of research exploring usage and behavior while interacting with complex error-sensitive systems, in so much as an action that couldn’t be undone once performed. This thesis explores the error-sensitive aspects of complexity within interactions of the administering of medical prescription activities at an intensive healthcare unit. The aim is to investigate the interactions of computer-supported cooperative work environments used for information transformation activities for medical prescriptions. The results reveal a number of HCI-related issues in which clinicians socially bypass system interactions by making incomplete data inputs while assuming a given level of understanding of other employees.

    Would you trust me if I lied to you in favor of charity?: The implication of Brand Trust when using Dark Patterns for charity2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Brand Trust is the trust consumers have in brands and have been previously proven to be affected negatively by dark patterns (i.e. design patterns used in websites to deceive their customers). This study is aimed to find out if Brand Trust is affected negatively by dark patterns when used for charity. The study is a between-group to determine Brand Trust based on six different scenarios (three using dark patterns for profit, three using dark patterns for charity) using the Brand Trust Scale that is divided into two dimensions, Fiability and Intentionality. This was measured in the form of two questionnaires. There were two groups that completed the questionnaires, one group that watched the scenarios for profit (for profit) and one that watched the scenarios for charity (for charity). The study consisted of 69 participants in total (37 completed the for-profit questionnaire; 32 completed the for-charity questionnaire). The hypothesis was that the group for-charity would have a higher value of Brand Trust. The results showed no significant difference between the two groups to support the hypothesis, however, an exploration of the results indicated that men have a higher Brand Trust in the dimension Intentionality and that the participants who valued themselves as really good at being source critical had a higher Brand Trust in the dimension Fiability.

    Framing Open Design through Theoretical Concepts and Practical Applications: A Systematic Literature Review2019In: Human-Computer Interaction, ISSN 0737-0024, E-ISSN 1532-7051, Vol. 34, no 5-6, p. 389-432Article, review/survey (Refereed)
    Abstract [en]

    This study reports on the results of a systematic literature review on ‘open design’ in academic fields including and beyond design and HCI. The review investigates how studies are framed as open design and open-source design (including ‘open hardware’): how researchers contribute to conceptual theorizing about open design or study its practical operationalization, in do-it-yourself ‘making,’ manufacturing and practices in-between these domains. Most of the papers reviewed were empirical studies from diverse fields. Open design was analyzed not only as contributions and solutions, but also as open-to-participate processes, openly shared processes, and open, closed, and modular (open and closed) outcomes. Various research fields presented an open design framing as an alternative to the status quo: new ways to do business and/or to foster socio-environmental sustainability. On the manufacturing side, open design was sought especially to accelerate innovation cycles; on the making side, it was espoused to foster democratization. However, the studies reviewed indicated that companies do not appear to develop much beyond business-as-usual. From the research perspective, the conceptual potential of open design to promote sustainability saw little practical exploration. Additionally, issues around open design community governance and ownership, safety and reliability of open outcomes require further investigation.

    Abstract [en]

    In this paper, we report the results from the psychologicalassessment conducted using a test battery composed of cognitiveand social wellbeing tests and questionnaires performed by usersand controls that participated in the AGNES project in Spain,Sweden and Greece at the beginning of the study and after thedeployment of the first prototype. The project carries out noveltechnological interventions in an emerging area in ageingresearch. The main innovation is the integration of differenttechnological components and social networking to provide anovel solution to the ageing population living at home. Themotivation was based on relevant findings on the psychology ofageing and the need for technologies to support the ageingpopulation. End-users have been heavily involved, providingdesign input, continuum evaluation and feedback. Theprojectfocuses on improving the mental and physical wellbeing ofelderly people living at home, who often suffer the effects ofsocial and physical isolation including cognitive decline, lowactivity levels and poor mood states. The main results were thatthe users but not the control participants improved cognitiveperformance andthe feeling of being treated with respect, beingindependent, self-realization and greater achievement.

    Interaction Design Issues in the Development and Assessment of Stress Management Apps: A Scoping Literature Review and Analysis2020In: CHIRA 2020 - Proceedings of the 4th International Conference on Computer-Human Interaction Research and Applications, SciTePress, 2020, p. 233-243Conference paper (Refereed)
    Abstract [en]

    A number of smartphone apps have been developed in recent years to help people cope with stress and promote mental well-being. Such apps have attracted significant attention in current research. However, interaction design issues, such as usability and user experience, have so far been relatively unexplored. This paper presents a meta-analysis of studies of mobile apps for stress management and mental well-being, specifically focusing on interaction design issues. Through a scoping literature search we selected the total of 46 articles, published in the last decade, for qualitative in-depth analysis. The analysis reveals that the main interaction design issues addressed in the papers are ease of use, user engagement, and privacy. Key opportunities and challenges for future work are discussed.

    A Multipurpose Goal Model for Personalised Digital Coaching2017In: Agents and Multi-Agent Systems for Health Care: 10th International Workshop, A2HC 2017, São Paulo, Brazil, May 8, 2017, and International Workshop, A-HEALTH 2017, Porto, Portugal, June 21, 2017, Revised and Extended Selected Papers, Springer, 2017, Vol. 10685, p. 94-116Conference paper (Refereed)
    Abstract [en]

    Supporting human actors in daily living activities for improving health and wellbeing is a fundamental goal for assistive technology. The personalisation of the support provided by assistive technology in the form of digital coaching requires user models that handle potentially conflicting goals and motives. The aim of this research is to extend a motivational model implemented in an assistive technology, into a multipurpose motivational model for the human actor who is to be supported, which can be translated into a multipurpose goal model for a team of assistive agents. A team of assistive agents is outlined with supplementary goals following the human’s different properties. A method for generating multipurpose arguments relating to different motives were developed, and implemented in a human-agent dialogue system. The results are exemplified based on a use case from an earlier pilot user study of the assistive technology. Future work includes user studies to validate the model.

    Human-Agent Dialogues and Their Purposes2017In: Proceedings of the European Conference on Cognitive Ergonomics 2017, New York, NY, USA: ACM Digital Library, 2017, p. 101-104Conference paper (Refereed)
    Abstract [en]

    A common conversation between an older adult and a nurse about health-related issues includes topics such as troubles with sleep, reasons for walking around nighttime, pain conditions, etc. Such a dialogue can be regarded as a "natural" dialogue emerging from the participating agents' lines of thinking, their roles, needs and motives, while switching between topics as the dialogue unfolds. The purpose of this work is to define a generic conceptual model of purposeful human-agent dialogue activity including different types of argumentation dialogues, suitable for health-related topics. This is done based on analyses of a scenario, persona and models of human behaviour. The model will be shared between the human and the agent, allowing for adaptation to the human's reasoning, needs and motives.

    Instrument-Oriented Approach to Detecting and Representing Human Activity for Supporting Executive Functions and Learning2017In: Proceedings of the European Conference on Cognitive Ergonomics 2017, New York, NY, USA: ACM Digital Library, 2017, p. 105-112Conference paper (Refereed)
    Abstract [en]

    The goal of this study is to develop a computer-interpretable model for activity detection and representation, based on existing informal models of how humans perform activity. Appropriate detection of purposeful human activity is an essential functionality of active assistive technology aiming at providing tailored support to individuals for improving activity performance and completion. The main contribution is the design of a model for detection and representation of human activities based on three categories of instruments, which is implemented as two generic and supplementary terminology models: an event ontology and a core ontology. The core ontology is extended for each new knowledge domain into a domain ontology. The model builds the base for personalization of services generated by the cooperative reasoning performed by a human collaborating with an intelligent and social software agent. Ongoing and future work includes user studies in the different application domains.

    Carefree in 2060: Pension saving for a full life2023Independent thesis Advanced level (degree of Master of Fine Arts (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The pension system in Sweden today is a very simple system. Taxed incomes generate pension incomes, paid out monthly after retirement. Yet the topic seems riddled with emotions; guilt, shame and anxiety over what you should or should not do. Increasing inflation, population age and climate change are projected to pose big threats to pensions in the coming decades. By 2060, pension incomes are projected to diminish substantially. Yet the future brings hope too; the gender gap in pension incomes is today at 30% and is projected to go down to 4% by 2040 as the changing view on women in the workplace and policy making is evening the (occupational) field.

    To learn about pension on the personal, professional and societal layers, I conducted conversations with professionals working for the pension agency, banks, savings solutions and researchers at economics and sociology departments at universities, as well as with individuals with pension planning on their minds (or not). The professionals argued that financial literacy teaches how simple the system is while the individuals feel overwhelmed and confused, showing that the system is not complicated but feels complicated. This dissonance became the space for designing.

    I propose to look at money as an actor we have a relationship with, to scale away guilt, shame or anxiety and leverage the positives. Through the strategic use of reflection, we learn about our ongoing relationship with money; formed in childhood, and shaped by everyday life planning towards the future. Thus, we grow towards a life where money serves us by investing in our values, hopes and dreams. As we change our financial behaviour today, we change our relationship in the future.

    The value of money does not start with the currency, but with the intention of use, in the hopes and dreams of a person that wants to spend their time with families and hobbies, not with stocks and funds. Looking at financial planning more holistically shows how the established system is biased, rejecting those that do not speak the language. We as designers can be mindful of this and make more inclusive tools to learn this financial language. Insofar the system can be changed is what I examine through speculative futures methods and designs.

    Towards Proactive Robot Behavior Based on Incremental Language Analysis2014In: MMRWHRI '14 Proceedings of the 2014 Workshop on Multimodal, Multi-Party, Real-World Human-Robot Interaction / [ed] Mary Ellen Foster, Manuel Giuliani, Ronald P. A. Petrick, 2014, p. 21-22Conference paper (Refereed)
    Abstract [en]

    This paper describes ongoing and planned work on incremental language processing coupled to inference of expected robot actions. Utterances are processed word-by-word, simultaneously with inference of expected robot actions, thus enabling the robot to prepare and act proactively to human utterances. We believe that such a model results in more natural human-robot communication since proactive behavior is a feature of human-human communication.

    Improving reading experience in digital newspapers2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Reading news on mobile devices has during the past decade transcended into an every- day activity, which induce greater demands on design and presentation of news. Several researchers have examined essential components in the area of digital newspapers, despite this, there are few newspapers that have switched to a reader-friendly format.

    The objective of this thesis is to evaluate how the reading experience in digital newspa- pers can be improved by abandoning the traditional structure of today’s printed newspapers. Based on numerous tests and studies, as well as support from literature, a set of guidelines has been produced as a result of this thesis.

    The design guidelines contain recommendations for optimal line size, typeface, point size, appearance, functionality, placement, recognition factor and packaging. To ensure quality, all guidelines were validated in order to prove that the reading experience had increased. An evaluation was performed that attempted to determine that.

    The statistic result of this thesis showed a significant difference in both reading speed and the subjective experience. However no significant difference could be seen regarding the reading comprehension. The conclusions made was that structure and design of content can influence both reading speed and reading experience.

    All design guidelines can be used as guidance when developing templates for digital newspapers.

    Designing experiences for virtual reality, in virtual reality: A design process evaluation2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Creating immersive experiences for virtual reality (VR) presents new design opportunities and challenges that do not appear when creating experiences on a screen. Creating prototypes and exploring concepts in VR is today limited to professionals with previous knowledge in 3D application development, and testing 3D experiences requires the usage of an Head-Mounted Display (HMD), which forces professionals to switch medium from the computer to an HMD. With new advances in this field, there have to be new solutions to these challenges. The goal of this thesis is to explore how VR technology can be utilized in the experience design process for VR. This is achieved through a literature study and conducting expert interviews, followed by a hardware evaluation of different HMDs and concept creation using rapid prototyping. From the interviews, a number of issues could be identified that correlates with the research from the literature study. Based on these findings, two phases were identified as suitable for further improvements; Concept prototyping and testing/tweaking of a created experience. Lo-fi and hi-fi prototypes of a virtual design tool were developed for HTC Vive and Google Daydream, which were selected based on the hardware evaluation. The prototypes are designed and developed, then tested using a Wizard of Oz approach. The purpose of the prototypes is to solve some of the issues when designing immersive experiences for HMDs in the suitable experience design phases that were identified by analyzing the interview results. An interactive testing suite for HTC Vive was developed for testing and evaluation of the final prototype, to verify the validity of the concept. Using Virtual Reality as a medium for designing virtual experiences is a promising way of solving current issues within this technological field that are identified in this thesis. Tools for object creation and manipulation will aid professionals when exploring new concepts as well as editing and testing existing immersive experiences. Furthermore, using a Wizard of Oz approach to test VR prototypes significantly improves the prototype quality without compromising the user experience in this medium.

    Designing Digital Nudges to Encourage Sustainable Decisions: Developing and Testing a Framework2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The awareness of environmental impacts lead to that organizations are starting to work towards UN's global sustainability goals. To influence customers into a more sustainable behaviour, organizations have the potential to look at nudging as a tool. A nudge is a way to alter peoples behaviour into taking a certain decision. However, since many organizations offer their service or product in the digital environment, such as websites or apps, increased knowledge of digital nudging is required. This thesis aims to establish a framework for how nudges should be designed and used on digital platforms to encourage sustainable decisions. The purpose is to enlighten designers of digital environment of the potential of nudges, pitfalls to avoid, and a general design process to follow. The framework is based on a literature study and interviews with people familiar with the concept of nudging. To examine how the framework works a case study is performed, this includes a workshop, performing a user research, developing prototypes and finally, conduct user tests. By testing the framework further methods could be found, this meant that more practical steps could be included in the framework. The result of this thesis shows that the framework proved to be useful and functional to use when designing digital nudges to encourage sustainable decisions.

    Investigating Attitudes of A Persuasive Eco-feedback Design for Digital Tasks2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sustainable development as a research topic is becoming more prevalent across different fields. From a computer science perspective sustainability can incorporate anything from how to develop low-resource-use algorithms to human-computer-interaction oriented applications for behavior change. Eco-feedback systems is the collective term for solutions that can give consumers feedback regarding the environmental impact from their product use. This thesis explores how Persuasive Systems Design (PSD) and eco-feedback can be merged for a digital context, i.e. during the use of computers and software. Two design prototypes were developed where one was considered neutral and the other had PSD applied. The prototypes were included in two separate questionnaires and distributed to capture participants' use intention and perceived persuasive potential of the different designs. Further on, the PSD prototype was used in a usability test and short interview with the intention to gather more opinions in addition to the questionnaire. The results show no significant difference in the response towards the neutral against the persuasive systems design. In total the perceived ease of use and usability score high, meaning the participants regard the design to be easy to use. The response differs greatly when it comes to usefulness and intention to use a similar system in the future. The results of this thesis give an indication of where the user interest is currently at. However, further evaluation and more research is necessary to develop stronger conclusions regarding how different users perceive eco-feedback systems.

    Cognition reversed: Robot learning from demonstration2009Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The work presented in this thesis investigates techniques for learning from demonstration (LFD). LFD is a well established approach to robot learning, where a teacher demonstrates a behavior to a robot pupil. This thesis focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. The robot should after demonstration be able to execute the demonstrated behavior under varying conditions.

    Several views on representation, recognition and learning of robot behavior are presented and discussed from a cognitive and computational perspective. LFD-related concepts such as behavior, goal, demonstration, and repetition are defined and analyzed, with focus on how bias is introduced by the use of behavior primitives. This analysis results in a formalism where LFD is described as transitions between information spaces. Assuming that the behavior recognition problem is partly solved, ways to deal with remaining ambiguities in the interpretation of a demonstration are proposed.

    A total of five algorithms for behavior recognition are proposed and evaluated, including the dynamic temporal difference algorithm Predictive Sequence Learning (PSL). PSL is model-free in the sense that it makes few assumptions of what is to be learned. One strength of PSL is that it can be used for both robot control and recognition of behavior. While many methods for behavior recognition are concerned with identifying invariants within a set of demonstrations, PSL takes a different approach by using purely predictive measures. This may be one way to reduce the need for bias in learning. PSL is, in its current form, subjected to combinatorial explosion as the input space grows, which makes it necessary to introduce some higher level coordination for learning of complex behaviors in real-world robots.

    The thesis also gives a broad introduction to computational models of the human brain, where a tight coupling between perception and action plays a central role. With the focus on generation of bias, typical features of existing attempts to explain humans' and other animals' ability to learn are presented and analyzed, from both a neurological and an information theoretic perspective. Based on this analysis, four requirements for implementing general learning ability in robots are proposed. These requirements provide guidance to how a coordinating structure around PSL and similar algorithms should be implemented in a model-free way.

    Representing behavior: Distributed theories in a context of robotics2007Report (Other academic)
    Abstract [en]

    A growing body of research within the field of intelligent robotics argues for a view of intelligence drastically different from classical artificial intelligence and cognitive science. The holistic and embodied ideas expressed by this research sees emergence as the springing source for intelligence. Similar perspectives, where numerous interactions within the system lead to emergent properties and cognitive abilities beyond that of the individual parts, can be found within many scientific fields. With the goal of understanding how behavior may be represented in robots, the present review tries to grasp what this notion of emergence really means and compare it with a selection of theories developed for analysis of human cognition. These theories reveal a view of intelligence where common notions of objects, goals and reasoning have to be rethought. A view where behavior, as well as the agent as such, is in the eye of the observer rather than given. Structures in the environment is achieved by interaction rather than recognized. In such a view, the fundamental question is how emergent systems appear and develop, and how they may be controlled.

    A formalism for learning from demonstration2010In: Paladyn - Journal of Behavioral Robotics, ISSN 2080-9778, E-ISSN 2081-4836, Vol. 1, no 1, p. 1-13Article in journal (Refereed)
    Abstract [en]

    The paper describes and formalizes the concepts and assumptions involved in Learning from Demonstration (LFD), a common learning technique used in robotics. LFD-related concepts like goal, generalization, and repetition are here defined, analyzed, and put into context. Robot behaviors are described in terms of trajectories through information spaces and learning is formulated as mappings between some of these spaces. Finally, behavior primitives are introduced as one example of good bias in learning, dividing the learning process into the three stages of behavior segmentation, behavior recognition, and behavior coordination. The formalism is exemplified through a sequence learning task where a robot equipped with a gripper arm is to move objects to specific areas. The introduced concepts are illustrated with special focus on how bias of various kinds can be used to enable learning from a single demonstration, and how ambiguities in demonstrations can be identified and handled.

    Emotion by Design: An exploration of evoking ‘relief’ through a mobile app2022Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Kurr is a foodtech startup developing a mobile app with the purpose of answering the question “what to eat?”. The company has built a brand identity in order to stand out among the more than 5,7 apps available in the biggest mobile app markets. As a part of the brand identity, the company aims to implement the emotion of ‘relief’ in the interactions between the app and its users. A unique attribute of ‘relief’ is that it must always appear immediately after some other aroused emotion. The objective of this study was to examine if it is possible to evoke ‘relief’ through a mobile app.

    Design thinking was the method applied in this study. The method has a big focus on the human, the users of the app in this case, by conducting interviews and user testing throughout the whole process. Phases of generating a big amount of ideas have alternated with phases of filtering out the best ones. To trigger the emotion of ‘relief’, the user flow was split into the following steps; 1. make it easy to get started, 2. motivate to keep on and charge up ‘joy’, 3. generate a climax of the preceding emotion, and 4. evoke the feeling of ‘relief. These steps were then implemented in a prototype.

    The prototype was later tested and the test results did not show evidence of how the emotion of ‘relief’ can be evoked through a mobile app, but it suggested that the result could differ if the tests were conducted in a real-life situation instead of a test environment. The research showed a significant result that the emotion of ‘joy’ was evoked when interacting with the prototype. The validity of the result should be further investigated though, with new user tests in a real-life environment and with a higher number of participants.

    Enhancing user experience through post-donation transparency2022Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Donating to charity is a phenomenon found in cultures and religions worldwide. Studies have examined how to attract donors, get them to engage, and eventually make a donation. But what happens after? The post-donation part of the process is less explored and often lacking in transparency toward the donor; where did the donation go, and how can the donors make sure it reaches the intended beneficiaries?

    This study investigated how post-donation transparency can enhance the user experience of donating money by identifying the donor’s needs and desires post-donation and fulfilling them in a design proposal. The Double Diamond model of design and its four phases were chosen to achieve this. In the first two phases, Discover and Define, the problem space was explored and defined through a literature study and initial interviews. The interview data was analyzed through the Affinity Diagram method resulting in two ”How might we”-questions. The needs and desires of users were also identified at this stage. A brainstorming session based on the ”How might we”-questions initiated the following, and last phases Develop and Deliver. Prototypes of different levels of fidelity were then created and tested on both users and experts before finally landing in a design proposal.

    Results showed that the elements added for creating post-donation transparency were appreciated by users and experts alike. A high score from a UMUX-LITE usability test suggested that the prototype was usable, elements in the prototype were pointed out for achieving transparency, and all participants expressed positive feelings after using the prototype. Therefore, the prototype was concluded to have achieved post-donation transparency within the frames of this study.

    Further studies are recommended as the final prototype was never tested on users. The hope is that more tests would give a better understanding of how user needs and desires could be achieved post-donation.

    How to efficiently onboard new users to a complex structured SaaS solution for data analytics2021Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    How can a user be onboarded seamlessly to a new complex SaaS solution for data analytics? This thesis covers how different design principles and onboarding frameworks can create an efficient user flow and user interface for onboarding users to the complex data analytic tool Link. A literature study was conducted to find good frameworks for onboarding and define usable concepts fitted to user experience and onboarding for a data analytics tool. Four personas of different user types were conducted to understand better what users need to reach value. The current issues with Links onboarding were tested with four user interviews and tests. Two expert heuristics evaluations were conducted on two different onboarding processes in two different Saas-solutions for data analytics. A user flow was conducted based on a literature study, the four personas, the user tests/interviews, and the heuristic evaluations. A lo-fi prototype was created. Two online surveys based on the lo-fi and user flow questions were created and distributed through email and online. One survey was directed to auditors, the target group for Link, and the other to working adults over 18. A hi-fi prototype was implemented into the existing application Link. Another set of user tests and interviews was conducted to improve the user flow further. In the end, a theory about the best user flow for onboarding users to a new complex data analytics tool was presented. The study shows the importance of knowing the product users and how to deliver them the value proposition within a new complex application.

    Evaluating Input Devices for Robotic Telepresence*2021In: ACM International Conference Proceeding Series, Association for Computing Machinery (ACM), 2021, article id 24Conference paper (Refereed)
    Abstract [en]

    Robotic telepresence (RT)-technologies enable users' to be physically and socially present in a remote environment. These systems consist of a robot with a base with wheels, cameras, speakers, microphones, and a monitor, remotely controlled via a computer. It is common for robotic telepresence systems to support multiple input devices, including keyboard, mouse, and game controller. However, to the authors' knowledge, there are no studies that have investigated the differences between the devices. This study investigates how four different input devices, mouse, game controller, and keyboard, affect performance and experience. The study consists of a controlled experiment where participants navigated a track with the four different input devices. Outlined in this article is a mixed-method study aimed to uncover the complexity of input devices, how various interaction design factors affect the performance, and the users' experience of different input devices. The study found the keyboard and game controller to be the overall best devices. Furthermore, this article highlights a need to understand how abilities received from previous experiences transfer to the usage of RT-technology.

    Non-technical users’ first encounters with a robotic telepresence technology: An empirical study of office workers2018In: Paladyn - Journal of Behavioral Robotics, ISSN 2080-9778, E-ISSN 2081-4836, Vol. 9, no 1, p. 307-322Article in journal (Refereed)
    Abstract [en]

    Robotic telepresence technologies are becoming ever more usable and affordable, as well as increasingly available as consumer products. In the coming years, a significant number of people are likely to encounter the technology for the first time, and many, if not most, of them are going to be “non-technical” users, that is, people who do not have special technical knowledge and skills of IT-professionals. Therefore, understanding how nontechnical users are getting familiar with robotic telepresence technology, how they perceive the technology, learn to control it, and relate it to their everyday work practices, is a topical research issue. This paper reports an empirical study, in which eight non-technical users, office workers who were not IT-professionals, were introduced to robotic telepresence and provided with a practical experience of acting as pilots of a remotely controlled robot. In follow up interviews the participants were asked to reflect on potential uses of the technology in their professional activities. The participants could successfully acquire basic navigation skills and reached a high level of spatial presence, but experienced problems with developing a "new body image”. When reflecting on the potential of the technology for supporting their work, the participants envisioned a number of benefits associated with remote physical mobility. The impact of the technology on the quality of workrelated social interactions was expected to be generally positive but somewhat limited.

    Employing the secondary task technique for measuring MRP pilots' cognitive load2018In: Proceedings of the 10th Nordic Conference on Human-Computer Interaction, ACM Press, 2018, p. 706-710Conference paper (Refereed)
    Abstract [en]

    Mobile Remote Presence (MRP) technologies make it possible for the user to be mobile in a remote environment, which opens up new possibilities for interaction. However, this new functionality comes at a cost. The need for MRP system users to pay attention to both telecommunication and device navigation increases their cognitive load. Assessing the cognitive load of MRP system users is a timely research issue, which is addressed in this paper both conceptually and empirically. We argue that Secondary Task (ST) techniques have certain advantages over existing Subjective Rating Scales (SRS) instruments, and report a study, in which a particular ST technique, a visual monitoring task, was employed to assess MRP pilot’s cognitive load. The empirical evidence from the study indicates that the method provides additional valuable insights into MRP pilots’ user experience.

    Abstract [en]

    The purpose of the study was to investigate how search/filtering of games and information for individual games could be improved on the website Gamilab. A survey was answered by 48 users of the website and user tests that examined the website’s usability and mental effort were conducted with four people without prior experience of the website. Based on literature, the results of the survey and the results of the user tests, a prototype was developed with more filtering options and more information for individual games. User tests to examine the prototype’s usability and mental effort were performed with the same participants as in previous user tests. A one-tailed paired samples t-test was conducted and the result showed a significant decrease in experienced mental effort for the prototype compared to the website. The user tests of the prototype also showed that the participants’ attitudes towards the website were generally positive, and the participants criticised the prototype less than the website.

    The Iterative Design of a Virtual Design Studio2008In: TechTrends, ISSN 8756-3894, Vol. 52, no 1, p. 74-83Article in journal (Refereed)
    Abstract [en]

    Our journey in the development of the Design eXchange has taken us a long way and there is a long way yet to go. We began with a vision for encoding design knowledge and creating online virtual design studio culture and found the wiki technology to be an exciting way to make progress towards many of our goals. On the other hand, our use of the wiki technology has itself inspired us to think differently about our original goals for the Design eXchange. Especially as a result of our experience with the wikis, we now realize the importance of allowing for analogies of public and private spaces in the virtual world to reflect physical world design culture and practice. We have understood the need for an ecology of wikis to support communities of virtual design studios and we have understood the need for thinking deeply about permissions in order to create circles of influence and awareness among designers in our online community.

    Evaluating the Game Approachability Principles for Designing Strategy Game Tutorials2020Independent thesis Advanced level (degree of Master (Two Years)), 300 HE creditsStudent thesis
    Abstract [en]

    The approachability of a game is determined by the ease of which a player may learn how to play it. Most often, the player is taught how to play a game during a specially designed first level, called the tutorial level. In order to evaluate the approachability of a game, Desurvire et al. created the Game Approachability Principles (GAP) and suggested that GAP could potentially also be used to design game tutorials. This was tested in this paper by using GAP during an iterative design process of a strategy game tutorial. Each tutorial iteration was user-tested and heuristically evaluated. This study suggested that the use of GAP during the design process had resulted in a successful game tutorial. However, as there was a difference between identifying and solving an issue, some revisions to GAP were suggested to improve the usage during design processes’.

    Older adults co-creating meaningful individualized social activities online for healthy ageing2018In: Building continents of knowledge in oceans of data: The future of co-created eHealth / [ed] Adrien Ugon, Daniel Karlsson, Gunnar O. Klein, Anne Moen, IOS Press, 2018, Vol. 247, p. 775-779Chapter in book (Refereed)
    Abstract [en]

    Social isolation and loneliness among older people is a growing problem with negative effects on physical and mental health. In co-creation with older adults individualized social activities were designed where older adults through computer mediated communication were able to participate in social activities without leaving their homes. Four types of activities were designed; outdoor activity, music event, visiting a friend and leisure activity. A participatory action research design was applied, where end users together with scientists from two research fields developed, tested and evaluated online participation in the activities. Usability and safety of the systems were major concerns among older adults. The evaluation pointed out that level of simplicity, usability and audio-video quality determined the level of satisfaction with the human interaction during the activity, thereby affecting the meaningfulness of the activity. The research presented in this paper constitutes the first step in a long-term research process aiming at developing a digital coaching system that gives older adults personalized support for increasing participation in meaningful social activities.

    Expected later information access invites shorter reading time and possible comprehension loss2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With the increased use of technology in society, there are concerns about how reading is affected by the constant access to an incessantly increasing amount of information. The present study examined how reading strategies and resulting memory and comprehension is affected by the belief that information to be remembered would continue to be available. In a within- participant experiment, twenty-seven participants were instructed to read six texts, and led to believe that they would have access to some of the texts while later answering comprehension questions. The results showed that participants spent significantly longer time reading texts they believed would not be accessible later, compared to those they believed they would have access to (p= .0007, d = 0.47). The participants did achieve slightly higher scores on the comprehension questions for the texts they believed they would not have access to, compared to the other condition, but the effect was not significant. The findings have implications for potential changes to reading strategies in response to increased use of technology as an external memory and information storage. I discuss how these strategies could have affected the raise of Fake News, inasmuch as increased information load from the Internet leads to a less meticulous reading style.

    Abstract [en]

    In the twenty-first century, we are literally surrounded by digital things and things that turn out to be digital – or have some digital parts or are parts of a larger system in which there are digital elements. We carry around mobile phones and watches; many also have additional music players, PDAs or PCs. We live in houses filled with digital networks and artefacts; we depend on infrastructures that are partly digital and have digital systems attached to them; we use public and private services that are digital, are based on digital infrastructures and have other digital systems attached to them; and we experience embedded, ubiquitous computing as we live in digitally enhanced environments that support our activities with or without our conscious control. The digital layer(s) in the world constitute a real world.

    Investigating a gesture based interaction model, controlling a truck with the help of gestures.2021Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper examines if a gesture based interaction model to control a heavy vehicle is a suitable mean of control. It looks at what the interaction model needs to make it reliable, trusted and usable. The methods that was used during this thesis included a literature review, prototype development and testing. To test this a prototype was developed in Unity. To handle the gesture recognition, it was paired with a Kinect 2.0, and the gesture learning was done with Visual Gesture Builder. With this we created two sets of gestures that were tested against each other. We found that a the gesture based interaction model was found intuitive, natural and seems to allow the operators to efficiently execute their tasks. However, there are two key aspects that needs to be taken in to consideration. Firstly the gesture recognition has to be at a really high standardas in having high recognition and well thought out gestures, both out of safety reason, but also to not cause frustration with the users. Secondly, the gestures themselves need to be designed in a way that will not cause fatigue, with poorly designed gestures the users would not be able to use this interaction model for a longer period of time.

    How to encourage stretching and breaks at work: Understanding long term usage of a behaviour change support system2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    We are spending more and more time seated at work, which increases the risk for health problems. Behaviour change support systems that encourage breaks and stretching at work have been used as interventions to try to reduce these problems. No previous studies had looked at how these systems were used for long periods of time. In this qualitative study based on ten interviews, we aimed for expanding our understanding of long-term usage of such systems by studying one called ‘Efons’. The results indicate that the main factors influencing long-term usage are timely reminders, the impact that the stretching exercises has on the users’ health and the education of the user about health recommendations. We also found elements we argue have the ability to influence long-term usage and currently do not exist in the system studied or its context of use, such as adapt the system to the needs of the user or provide education about why these systems are useful.

    How does navigation system behavior influence human behavior?2019In: Cognitive Research: Principles and Implications, E-ISSN 2365-7464, Vol. 4, no 5Article in journal (Refereed)
    Abstract [en]

    Navigation systems are ubiquitous tools to assist wayfinders of the mobile information society with various navigational tasks. Whenever such systems assist with self-localization and path planning, they reduce human effort for navigating. Automated navigation assistance benefits navigation performance, but research seems to show that it negatively affects attention to environment properties, spatial knowledge acquisition, and retention of spatial information. Very little is known about how to design navigation systems for pedestrian navigation that increase both navigation performance and spatial knowledge acquisition. To this end, we empirically tested participants (N = 64) using four different navigation system behaviors (between-subject design). Two cognitive processes with varying levels of automation, self-localization and allocation of attention, define navigation system behaviors: either the system automatically executes one of the processes (high level of automation), or the system leaves the decision of when and where to execute the process to the navigator (low level of automation). In two experimental phases, we applied a novel empirical framework for evaluating spatial knowledge acquisition in a real-world outdoor urban environment. First, participants followed a route assisted by a navigation system and, simultaneously, incidentally acquired spatial knowledge. Second, participants reversed the route using the spatial knowledge acquired during the assisted phase, this time without the aid of the navigation system. Results of the route-following phase did not reveal differences in navigation performance across groups using different navigation system behaviors. However, participants using systems with higher levels of automation seemed not to acquire enough spatial knowledge to reverse the route without navigation errors. Furthermore, employing novel methods to analyze mobile eye tracking data revealed distinct patterns of human gaze behavior over time and space. We thus can demonstrate how to increase spatial knowledge acquisition without harming navigation performance when using navigation systems, and how to influence human navigation behavior with varying navigation system behavior. Thus, we provide key findings for the design of intelligent automated navigation systems in real-world scenarios.
